Electron-deficient acyclic enamine derivatives react with electron-rich 1-arylalkynes using cationic gold(I) species as catalysts in an intramolecular process to form annulated 1-amido-substituted indene derivatives as the major products. Yields for this process range between 21% and 98%. In some cases, a two-step process that includes a subsequent alkene isomerization is needed.
缺电子的无环烯胺衍生物在分子内过程中使用阳离子金(I)类作为催化剂与富电子的1-芳基炔烃反应,形成环化的1-酰胺基取代的茚衍生物作为主要产物。此过程的产率在21%到98%之间。在某些情况下,需要包括随后的烯烃异构化的两步法。
